Claim 1 is objected to because of the following informalities: Claim 1 recites the phrase “at least one selected from Ga, G2, Ja, J2, Q, Qb, and Qc is N”. Applicants are advised to amend this phrase to recite “at least one selected from Ga, G2, Ja, J2, Q, Qb, or Qc is N”. Appropriate correction is required. Claim 1 is objected to because of the following informalities: Claim 1 recites the phrase “formula I;”, see Page 6. Applicants are advised to amend this claim to recite “Formula I;”. Appropriate correction is required. Claim 6 is objected to because of the following informalities: Claim 6 recites Formula 2a as: PNG media_image1.png 92 128 media_image1.png Greyscale However, the claim recites the variable R1 in Formula 2a in the body of the claims as R1. In order to avoid any potential confusion, Applicants are advised to amend Formula 2a to recite “R1, i.e. consistent with the notation present in remaining formulas of the claim. Appropriate correction is required. Claim 6 is objected to because of the following informalities: Claim 6 recites the phrase “at least one Q*=N;”. Applicants are advised to amend this claim to recite “at least one Q* is N;”. Appropriate correction is required. Claim Rejections - 35 USC § 103 The following is a quotation of 35 U.S.C. 103 which forms the basis for all obviousness rejections set forth in this Office action: A patent for a claimed invention may not be obtained, notwithstanding that the claimed invention is not identically disclosed as set forth in section 102 of this title, if the differences between the claimed invention and the prior art are such that the claimed invention as a whole would have been obvious before the effective filing date of the claimed invention to a person having ordinary skill in the art to which the claimed invention pertains. Patentability shall not be negated by the manner in which the invention was made. The factual inquiries set forth in Graham v. John Deere Co., 383 U.S. 1, 148 USPQ 459 (1966), that are applied for establishing a background for determining obviousness under 35 U.S.C. 103 are summarized as follows: 1. Determining the scope and contents of the prior art. 2. Ascertaining the differences between the prior art and the claims at issue. 3. Resolving the level of ordinary skill in the pertinent art. 4. Considering objective evidence present in the application indicating obviousness or nonobviousness. This application currently names joint inventors. In considering patentability of the claims the examiner presumes that the subject matter of the various claims was commonly owned as of the effective filing date of the claimed invention(s) absent any evidence to the contrary. Applicant is advised of the obligation under 37 CFR 1.56 to point out the inventor and effective filing dates of each claim that was not commonly owned as of the effective filing date of the later invention in order for the examiner to consider the applicability of 35 U.S.C. 102(b)(2)(C) for any potential 35 U.S.C. 102(a)(2) prior art against the later invention. Claims 1, 3-9, 12, and 16-25 are rejected under 35 U.S.C. 103 as being unpatentable over Ogiwara et al (US 2020/0035922). Regarding claim 1, Ogiwara et al discloses the following compound (Page 104): PNG media_image2.png 360 417 media_image2.png Greyscale . This compound corresponds to the compound represented by recited Formula I: PNG media_image3.png 240 350 media_image3.png Greyscale , where: RI, one (1) RII, RIII, and RIV are hydrogen; RVI, RVII and RVIII are hydrogen; and RV is hydrogen; The second substituent RII is: PNG media_image4.png 339 504 media_image4.png Greyscale . This substituent corresponds to Formula I-0 of the claims: PNG media_image5.png 274 512 media_image5.png Greyscale , where: m is zero (0); n is zero (0); o is zero (0); Ga is N; Ja is CRa, where Ra is a C6 aryl; Qb is CR1, where R1 is a C6 aryl; Qc is N; Z is Q, where Q is N; Qa is CRa, where Ra is a binding site. In the compound disclosed by the reference, substituent RII corresponds to Formula I-0, while the claims require that substituent RV corresponds to Formula I-0. Accordingly, the compound disclosed by the reference and that claimed are isomers - compounds having the same radicals in physically different positions on the same nucleus, and the courts have held, as found in In re Wilder, 563 F.2d 457, 195 USPQ 426 (CCPA 1977), that compounds which are isomers “are generally of sufficiently close structural similarity that there is a presumed expectation that such compounds possess similar properties”. In light of the case law cited above, it therefore would have been obvious to one of ordinary skill in the art that the compound disclosed in the present claims is but an obvious variant of the compound disclosed in the reference and thereby one of ordinary skill in the art would have arrived at the claimed invention. Alternatively, it is noted that the compound disclosed by the reference is but one embodiment, and attention is directed to Formula (21A) (Page 39): PNG media_image6.png 282 294 media_image6.png Greyscale , where R21 can be a substituted heteroaryl and R22 can be hydrogen ([0243] and [0235]-[0236]). Furthermore, the reference discloses that the compound can be symmetric about the x-y, i.e. ([0210]): PNG media_image7.png 246 176 media_image7.png Greyscale . Accordingly, the disclosure of the reference encompasses an embodiment where substituent RV in recited Formula I is a phenyl substituted triazine and substituent RII is hydrogen. While the reference fails to exemplify the presently claimed compound nor can the claimed compound be "clearly envisaged" from the reference as required to meet the standard of anticipation, nevertheless, in light of the overlap between the claimed compound and the compound disclosed by the reference, absent a showing of criticality for the presently claimed compound, it is urged that it would have been within the skill level of one of ordinary skill in the art, to use the compound which is both disclosed by the reference and encompassed within the scope of the present claims and thereby arrive at the claimed invention. Regarding claim 3, Ogiwara et al teaches all the claim limitations as set forth above. As discussed above, RI, RII, RIII, and RIV are hydrogen. Regarding claim 4, Ogiwara et al teaches all the claim limitations as set forth above. From the discussion above, the reference discloses a compound corresponding to Formula Ia: PNG media_image8.png 238 346 media_image8.png Greyscale .

From the discussion above, the reference discloses a compound corresponding to Formula 3: PNG media_image11.png 246 352 media_image11.png Greyscale . Regarding claim 9, Ogiwara et al teaches all the claim limitations as set forth above. From the discussion above, the reference does not disclose a compound corresponding to Formula Ig: PNG media_image12.png 284 356 media_image12.png Greyscale . However, attention is directed to Formula (21A) (Page 39): PNG media_image6.png 282 294 media_image6.png Greyscale , where R22 and R23 can be a C6 aryl group ([0236]). Accordingly, the disclosure of the reference encompasses recited Formula Ig. Regarding claim 12, Ogiwara et al teaches all the claim limitations as set forth above. Additionally, the reference discloses an organic light emitting device, where the emitter layer comprises first and second compounds (Abstract).

The discussion with respect to Kim et al as set forth in Paragraph 12 above is incorporated here by reference. Regarding claim 25, Kim et al teach all the claim limitations as set forth above. Additionally, the reference discloses a process of forming an electroluminescent element comprising the disclosed compound. However, the reference does not disclose that the process utilizes a vacuum evaporation method as recited in the present claims. Zhang et al discloses that typically, an organic light emitting device is manufactured by a vacuum evaporation process ([0003]). In view of this teaching, it would have been obvious to one of ordinary skill in the art to deposit the compound disclosed by Kim et al via vacuum deposition as doing so would amount to nothing more than use of known method for its intended use, in a known environment to accomplish entirely expected results. Response to Arguments Applicant's arguments filed 6/17/2025 have been fully considered but they are not persuasive. In light of the amendments to the claims, the 35 U.S.C. 112 (b) rejection set forth in the previous Office Action is withdrawn. Furthermore, in light of the amendments to the claims, the 35 U.S.C. 102 and obviousness-type double patenting rejections set forth in the previous Office Action are withdrawn. Applicants argue that as amended, Kim et al does not disclose the compound recited in claim 1. However, as discussed in the rejections above, the reference discloses the following compound: PNG media_image14.png 424 411 media_image14.png Greyscale RV is a methyl group and therefore, does not correspond to Formula I-0 of the claims: PNG media_image5.png 274 512 media_image5.png Greyscale . However, the compound disclosed by the reference is but one embodiment and attention is directed to the following general formula for the compound ([0014] – Formula 1): PNG media_image15.png 264 356 media_image15.png Greyscale , where R1 can be heteroaryl having 5 to 60 nuclear atoms. Paragraph [0031] defines heteroaryl as including triazinyl, i.e. PNG media_image16.png 261 342 media_image16.png Greyscale . The triazinyl substituent corresponds to Formula I-0 of the claims: PNG media_image5.png 274 512 media_image5.png Greyscale , where: m is zero (0); n is zero (0); o is zero (0); Ga is N; Ja is CRa, where Ra is hydrogen; Qb is CR1, where R1 is hydrogen; Qc is N; Z is Q, where Q is N; and Qa is CRa, where Ra is a binding site.
